BEIJING, Aug. 12 (Xinhua) -- China on Monday urged the United States to immediately stop interfering in Hong Kong affairs.

The remarks came as Hua Chunying, a spokesperson with the Chinese Foreign Ministry, responded to a query about the "color revolution" label that Hong Kong has tended to wear recently.

As many people in Hong Kong have pointed out, the ordinance amendment issues have changed in their essence, and now bear the features of a "color revolution," said Zhang Xiaoming, director of the Hong Kong and Macao Affairs Office of the State Council last Wednesday.

The U.S. side has frequently made irresponsible remarks on Hong Kong affairs, which confused black from white and incited troubles, Hua said.

Some key politicians and diplomatic officials from the United States, who have interacted with pro-democracy rioters and unjustly accused the Chinese central government, are conniving violence and illegal acts jeopardizing prosperity and stability of Hong Kong, she added.

With all the obvious facts, Hua said she wonders "what the real intention of the U.S. is" and "what the U.S. is using Hong Kong for."

The spokesperson reiterated that Hong Kong belongs to China and Hong Kong affairs are purely China's internal ones.

China urges the United States to abide by international law and basic norms governing international relations, and promptly stop meddling in China's internal affairs, she said.
